Created attachment 204268 [details] Sample ODP The attached ODP presentation has: - a 3D object, - a regular shape, - a grouped shape containing a 3D object and a regular shape, ...with animations defined on each. Save it as PPTX. When opening the result in Impress, you will see the 3D objects are gone, this is expected, as they are specific to Impress. Opening the result in PowerPoint fails. The 3D objects aren't exported, but the animations on them are, causing invalid shape reference to be written into the PPTX. If a grouped shape only consists of 3D objects, an empty group shape is exported, which is still OK, the problem is only animations on individual objects. Observed using LO 26.2.0.0.alpha1+ (2025-11-22), 4.0.0.3 / Windows.
